Median TIMP2 IGFBP7 at H6 was of no added value since it was not significantly different in patients who developed CS-AKI (n = 23 true positives for ∆pCrpostCPB-H6) and those who did not (n = 8 false positives): 0.42 (IQR 0.20;0.81) versus 0.45 (IQR 0.09;1.56) (ng/mL)2/1000; p = 0.70. This evidence concerns the gene IGFBP7 and acute kidney injury.
